MR24-30 2.4GHz LoRa Module with MLRS Firmware

The mR24-30 is a high-performance 2.4GHz LoRa module featuring the STM32G431KB MCU and mLRS firmware, designed for reliable long-range communication in UAVs and other remote control applications. Powered by the LoRa SX1281 with TCXO and enhanced by the PA/LNA SKY68383-11, this module offers multiple RF power options ranging from 13dBm to 30dBm (1000mW), allowing for flexible deployment in various environments.

With bi-directional Serial MAVLink communication via TX1/RX1 and RC output options (CRSF or SBUS) via TX2, the mR24-30 provides robust connectivity and control for your devices. The compact design includes an IPEX MHF-1 antenna connector and a one-button interface for DFU mode and binding. This module is powered by a 4.5-13V DC supply, with a power dissipation of 360mA at 5V.

Designed for ease of use, the mR24-30 includes LED status indicators for quick setup and operation. Whether you’re managing a UAV fleet or enhancing a remote-controlled project, this LoRa module is built for reliable performance and versatility.
